摘要
Abstract
More attention is paid to the micro-grid with the continuous development of new energy utilization.A protection scheme for micro-grid in island operation is proposed based on the negative sequence directional component.This novel protection scheme only needs to compare the phase difference between negative sequence voltage and current in relay location,and it has a good adaptation of fault resistance.The simulation results based on PSCAD/EMT-DC prove the correctness of the conclusions.关键词
